DUMPING-GAR;

Specification of Letters Patent.

Patented Sept. 17, 1907.

To all whom it may concern:

Be it known that 1, CHARLES B. PETELER of the United States, residin acitizen 1 at Minneapolis, Hermepin county, Minnesota, have inventedcertain new and useful Improvements in following is a full, clear, andexact descript Du mp-Oarsiof which the ion, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to dump cars and has particular ranged to be raisedwhen the body is tilted to the load.

The object of my invention is to provide a having movable side boards,with improved .automatical body when the latter is tilted and to swing Il l l l t l reference to dumpcars in which the side board is an i t idischarge 5 dump car means for ly raising the side boards above the carsaid side board into a plane substantially parallel with the floor ofthe car at such times to give maximum clearance for ,the discharge ofmaterial.

A further object is to provide a dump car w tolnatic side board raisingdevice which may be manually operated to raise as before mentioned,

l r l ith an aui the side- J board above the car body when the latter isin upright position, in order that material may without raising it abovethe car side With-these objects in view, my the improvements in dumpcars hereinafter and particularly pointed out in the claims.

boards.

be loaded therein invention consists in described reference to theaccompanying drawings forming a part My invention will be more readilyunderstood by I embodying my improvements; Fig. 2 is a plan view of oneend of the car shown in Fig. 1; and Fig. tion showing the car in tiltedor dumping pos 3 is an end elevaition Referring to the drawings, 1indicates the car truck,

whereof 2 is the end beam, and 3-3, the

side sills.

The truck is mounted upon suitable running gear, as

the wheels 3.

4 indicates the coupler attached to the draft sills 5.

Upon the draft sills 5 are arranged a number of brackets 6, upon whichthe car body 7 is pivoted. The

preferred or bed 8,

The latter are secured to the car body by suitable means whichconstitute my improved device for automatically raising said sideboards, as above mentioned, when the car is tilted to discharge thecontents thereof.

Each of the two side boards of the car is equipped at both ends with mynovel operating mechanisms. these are identical in construction andoperation the scription of the devices attached to one side I sufficefor all.

As de- JOZLICl will Secured to each end of the side board is an arm 14rigidly connected thereto, being braced by a bar 12, which latter isriveted or bolted to the arm 14 as at 13. This forms a rigid frame orarm upon the end of the side board with the end of the arm 14 preferablyprojecting therebeyond. This rigid arm is pivoted, as at 15, to a longlever 16, pivoted at its inner end 17 to a suitable bracket 18 fastenedupon the end board 9 of the car body. Pivoted to the lever 16, as at 16,is a fulcrum bar, support or prop 20, the lower end of which rests uponthe side beam 3 of the truck when the car body is tilted. Suitable meansare provided to maintain the lower end of the bar 20 in proper position,that is, in engagement with the side beam In the drawings I haveillustrated, for this purpose a bar or lever 21 fastened at one end tothe bar 20, as at 22, and pivoted to the car body at its opposite end.However I need not rely upon such a device, but may provide a socketsuitably arranged upon the truck to receive the lower end of the bar 20.The side board lifting and turning device is completed by a link 25,connecting the end of the arm 1 1 with the bar 20 and therewith forminga toggle-lever.

The arms and levers, as described, are so proportioned that when the caris in upright position the side boards 10, which run from end to end ofthe car, are held tightly in place. The arms 14 and 16, beingpractically in a straight horizontal line, hold the sides firmly, nomatter how great theinternal pressure from the load contained in thecar, and the upward thrust of the bars 20 and of the links 25 upon theends of the arms 14, provents the side from turning upon the pivots 15.HOW- ever, on account of the relation of the several arms and levers andthe arrangement of their pivotal points, as soon as the car body beginsto tilt, the device so operates as to throw the lower edge of the sideboard out wardly, thereby relieving, to a great extent, the friction ofthe load upon said side board.

When the car body is tilted, as shown in Fig. 3, the lower end of theprops 20 rest upon the side sill 3 of the truck, which prevents furtherdownward movement Of said props, while the bar 21 prevents displacementof the ends of the bars 20 upon said side sill. As the car is tilted,the end pivots 1'7 move outwardly and downwardly, following the arcs ofcircles of which the pivotal axis 6 of the car body is the center. Thiscauses the lovers 16 to rock upon the pivots 16, throwing their outerends upwardly. This increases the distance between the pivot points 15and the lower ends of the links 25. Hence the links 25 and the arms 14act as toggle levers to turn the side board 10 upon the pivots 15 untilthe board assumes a position substantially parallel with the floor ofthe car. When the car is righted, gravity, together with the upward andthe inward swing of the pivots 17, returns the parts to normal positionsas shown in Fig. 1. Chains 7 are provided to normally maintain the carin upright position. These are unhooked when the car is to be dumped.

When the material is being loaded into the car by hand, the side boardsmay be raised manually in order that the workmen may be saved the extralabor of raising the heavy material to the additional height necessaryto toss the same over the side boards, To raise the side board it is butnecessary to give the lower ends of the props or fulcrum bars 20 anoutward and upward pull. This will raise the side board above the car ina manner similar to that just described, when the car is tilted;

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

In a dumping car, a truck, a car body adapted to be tilted thereon todischarge its load, and a side board for said car body, in combinationwith swinging supports for said side board, props pivoted at one end torespective swinging supports, and toggle levers, connecting said sideboard with said props; the whole so arranged as to increase the anglebetween said swinging supports and said props, when the car is tilted,thereby straightening'said toggle lovers to turn said side board,substantially as described.
